CNOOC completes construction of derrick lay vessel Hai Yang Shi You 201Vessel & ROV News // June 6, 2012
GustoMSC has announced that on 15 May CNOOC finished construction of the GustoMSC-designed derrick lay vessel Hai Yang Shi You 201, including the GustoMSC 4,000 tonne heavy lift offshore crane.
The vessel was built at Rongsheng Shipyard and completed outfitting at COOEC’s Qingdao yard. It will start its first operations in the China Sea and South East Asian waters.
Hai Yang Shi You 201 is a GustoMSC DPV7500 type deepwater crane/pipelay vessel. The DPV7500 is capable of laying rigid pipe in up to 2,000m water depth. It is designed to provide high redundancy meeting DPS-3 requirements.
The pipelay capacity is provided for single and double jointing of 6-60in pipes including a storage facility of 9,000 tonnes, a tensioning system of 2 x 200 tonnes complemented by a 400 tonnes A&R capacity. A GustoMSC designed fixed truss type stinger stinger adjustment system is situated at the aft of the vessel.
The vessel is equipped with a GustoMSC GDC-4000-ED derrick crane that combines high capacity and high outreach with a short minimum radius. The proprietary crane is provided with the GustoMSC bogie wheel system which provides unrestricted slewing of the crane and makes it ideally suited for installation of offshore jackets and modules, wind turbine parts, its own stinger or other heavy components.
The GDC-4000-ED is capable of lifting 3,500 tonnes @ 33m fully revolving. In tieback mode the lifting capacity is increased to 4,000 tonnes @ 43m over the stern.
Additional lifting versatility is included with an auxiliary hoist with a splittable block, suitable for SWL of 800 tonnes and 500 tonnes for deepwater applications and two whip hoists with SWL of 50 tonnes and 70 tonnes.
The new vessel has a length overall of 204.65m, length between perpendiculars of 185.0m, breadth moulded of 39.2m, depth of 14.0m, operational draught (pipe laying) of 7.0–8.0m and draught in crane lifting mode of 8.0–9.5m.
